Application of LVIS stent -assisted coil embolization in intracranial wide -necked small aneurysms

Abstract

Objective To explore the application value of LVIS stent in interventional treatment of intracranial wide-necked small aneurysms, and evaluate its safety and effectiveness. Methods A total of 11 patients with intracranial wide-necked small aneurysms, admitted to and received LVIS stent-assisted coil embolization in our hospital from November 2014 to June 2015, were chosen in our study. Their clinical data and treatment effects were retrospectively analyzed. Results All operations were successful in 11 patients; 11 LVIS stents were deployed; Raymond classification right after the surgery hinted grade I in 4 aneurysms, grade II in 5 aneurysms, and grade III in 2 aneurysms. There were 2 patients enjoying suboptimal opening of LVIS stents. Raymond classification 6 months after the surgery hinted grade I in 8 aneurysms and grade II in one aneurysm. Modified Rankin scale 6 months after the surgery indicated that 10 patients had 0 point and one patient had 2 points. Conclusion The LVIS stent is safe and effective for treatment of intracranial wide-necked small aneurysms; short-term effect is good; the technique requirements of stent releases are relatively high and require more attention of clinicians.
